ADM809SAKS-REEL7

Supervisors Overview

The ADM809SAKS-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for microprocessor supervision in SC-70-3 packages. It features a fixed threshold voltage of 2.93 V and an overvoltage threshold of 2.96 V, with a reset delay time of 240 ms. The device operates within a maximum supply voltage of 5.5 V and maintains an accuracy of 1.5%. It draws a working supply current of 60 uA and functions across a temperature range of -40 C to +125 C. The output type is push-pull, and it lacks manual reset, watchdog timer, or battery backup switch capabilities.

Supervisors Feature Summary

• Provides fixed voltage supervision with a 2.93 V threshold for reliable power monitoring
• Features a push-pull output configuration for direct interface with digital logic
• Operates efficiently with low quiescent current consumption of 60 uA
• Ensures stable performance across extended industrial temperature ranges

Supervisors Applications

• Microprocessor system power monitoring
• Portable electronic device power management
• Industrial control system voltage supervision

Supervisors Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm package type and reel specifications. Confirm RoHS compliance status through the manufacturer's datasheet. Check regional availability restrictions as distribution may vary by location. Ensure the ordering information matches the specific SC-70-3 package variant required for your design.

Supervisors Selection Notes

Select this component when a fixed 2.93 V threshold is required for single-input voltage supervision. Consider the SC-70-3 package size for space-constrained designs. Evaluate the 240 ms reset delay against system startup requirements. Verify that the 5.5 V maximum supply voltage aligns with the target application's power rail specifications.

Supervisors Part Context

This component belongs to the ADM809 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and package options for different power monitoring needs. The ADM809SAKSZ-REEL7 specifically denotes the 2.93 V threshold variant in a reel packaging format, suitable for automated assembly processes.

Supervisors Replacement Considerations

Other ADM809 variants with different threshold voltages (e.g., ADM809RAKSZ for 2.63 V or ADM809TAKSZ for 3.08 V) may serve as functional substitutes if the threshold requirement differs. Ensure pin compatibility and package similarity when considering alternatives.
